Upon the clotting roller shaft 9 are mounted by means of theirbosses the friction discs or bowls 29 of such diameter as to keep the doffer teeth justclear of the aspirator tube and which are in driving contact with the surface of the aspirator 11. The dofling roller 8 is therefore rotated by the'aspirator, as is also the stripping roller 27, and this drive is not affected by desired adjustment ofthe brackets 22, which the aspiratorv tube. I V

Upon the plates 14 at either side of the cylinder are formed suitable surfaces to receive the semicircular supports 22 and fitted with screws 20 which engage in slots 21 formed in, the semicircular supports 22.

These h'ave formed" at their upper ends the bifurcated bearings 23 forthe shaft 9 of the doifing roller. at 24 and formed the shaft 26 of 27.7 Adjustment of the supports 22 by the screws 20 will thus ensure that the do'fling roller'8 and brush 6 are always in the desired relation and'thisadjustment does not disturb the stripping roller 27 which remains in contact'with the aspirator 11 and in the requisite proximityto the teeth 10 of the dolfing roller 8, whilst the latter is easily removable when desired. The ends of the brackets 22 may be formed as shown in Fig- Each bracket is extended with open bearings 23 for ure 1 at 28, these ends thus forming are ceptacle for thedoifing roller when the latter with its shaft is removed from its operative. position for access to the brush 6, say

for inspection or readjustment of the latter,

In addition to the advantage of the savingof power in driving the brush 6, and also the saving of wear and tear thereon consetquent upon the decreasedcspeed thereof, it

as found that a very slight air current is suflicient to clear the doifing roller teeth '10,, with the'assistance of the stripping roller 27. The air currentmay therefore, be reducedconsiderably, and indeed may only'be maintained in a degree sutlicient to ensure that the fly shall be kept within the cover and prevented from getting out and settling on the exterml parts of the machine.

This reduction is further aided by the fact that where the doffing roller is introduced, nearly the whole of the waste is collected on the teeth thereof and does not obstruct the passage of air through the perforations exposed within the casing until it and they reach the stripping position. In the arrangement where the dofiing roller is absent, the wholeof the Waste is drawn on to the perforations immediately they are ex are concentric with "is fitted as above described, and the dofling the small stripping roller ings in said arms'and the brush and asplrator drum, and a stripforations and the fan speed, may be reduced by half andstill sufiice to strip the dofler and keep themachine clean.

Each combing head of a combing machine roller shaft 9 may extend across one or more of such heads.
